// The accessibility APIs are handled differently. A class might conform to both 
// NSAccessibility (containing accessibility properties) and individual 
// accessibility protocols (containing accessibility methods with the same 
// names as the properties). This should not compile. To avoid the problem, we 
// import setters and getters instead of the accessibility properties from 
// NSAccessibility.
